Trenberth: "“The reprieve we’ve hadfrom warming temperatures in the last few years will not continue." ... He warns now 'missing' heat will haunt us. "“The heat will come back to haunt us sooner or later,” says NCAR scientist Kevin Trenberth, the lead author....Earth’s surface temperatures have largely leveled off in recent years....

That means about half the total amount of heat is unaccounted for."...

On Trenbeth's participation in the UN 2007 Nobel Prize winning report: "The IPCC's AR4 chapter lead was Kevin Trenberth, who features prominently in the Climategate emails.

The data were gathered from weather stations around the world and then adjusted to take account of variables in the way they were collected. The revised figures were kept, but the originals — stored on paper and magnetic tape —

The admission follows the leaking of a thousand private emails sent and received by Professor Phil Jones, the CRU’s director. In them he discusses thwarting climate sceptics seeking access to such data. In a statement on its website, the CRU said:

“We do not hold the original raw data but only the value-added (quality controlled and homogenised) data.”

So much for settling questions and resolving debates with science,” he said.

Jones was not in charge of the CRU when the data were thrown awayin the 1980s, a time when climate change was seen as a less pressing issue.

The lost material was used to build the databases that have been his life’s work, showing how the world has warmed by 0.8C over the past 157 years. He and his colleagues say this temperature rise is “unequivocally” linked to greenhouse gas emissions generated by humans.

Their findingsare one of the main pieces of evidence used by the Intergovernmental Panel on Climate Change, which says global warming is a threat to humanity."
